2. Description of the Related Art In general, various types of card connectors for connecting a PC card having various functions to an electronic device have been developed in order to enhance both miniaturization and expandability of an electronic device such as a notebook computer. ing. Such a card connector generally includes a connector frame having a pair of guide arms forming a slot for inserting a PC card and a header portion integrally connecting the guide arms, and the card frame is printed via the connector frame. Screwed to the substrate. In the case of a card connector in which two headers are overlapped with each other to accommodate PC cards of various thicknesses, these headers and guide arms are integrally connected by a bracket formed of a thin metal plate. At the same time, it is screwed to the printed circuit board through such a bracket. In each case, a slight gap is formed between the card connector and the printed circuit board.

Even in this state, the polarity of the header body 14a, that is, the insertion direction of the PC card C is maintained the same as that shown in FIG. 1, and the arrangement of the mounting holes and the like of the printed circuit board P can be used without change.

In the above-described embodiment, female threads are formed on the inner peripheral surfaces of the cylindrical projections 79, 89 forming the connecting portion of the mounting bracket. A male screw may be formed on the outer peripheral surface of the. In this case, the cylindrical projections 79 and 89 may have a solid structure, and a mounting nut is used as a fastener. Further, a rivet may be used as a fastener instead of the mounting screw 100 or the mounting nut. In this case, it is not necessary to form a female screw or a male screw on the cylindrical projections 79, 89.
